JAR-WRENCH.

Specification of Letters Patent.

Application led September 8, 1916. Serial No. 119,111.

mary object is to provide an improved device, of simple and cheapconstruction, which is well adapted to the purpose of loosening ortightening closures of varying sizes.

The invention is illustrated in its preferred embodiment in Vtheaccompanying drawing, in which- Figure l represents a plan view of ajarwrench constructed in accordance with my invention, the dotted lineindicating the top or Closure of a jar; Fig. 2, a bottom plan A view ofthe device, showing the levers more widely separated to admit a largercan-top; Fig. 3 a side edge elevational view of the device, viewing theside which is at the upper portion of the figure in Fig l; and Fig. 4, asectional view, taken as indicated at line 4 of Fig. 1.

In the preferred construction, the invention comprises a pair of levers,or jaws, A and B, provided, respectively, with handles A and B. One ofthe levers, preferably the lever A, is provided at its pivot end with alaterally extending arm, or pivot-lug, l, and the other lever isconnected therewith by a pivot 2. Also, one of the levers, preferablythe lever A, is provided with two gripping-lugs 3 and 4, while the otherlever is provided with a single gripping-lug 5.

The levers are preferably stamped from sheet-metal. The metal at theouterv lateral edge of the lever A is bent downwardly to form a flange,which is suitably shaped to provide the bearings, or gripping-lugs, 3and 4, it being understood that the flange is interrupted between thebearings 3 and 4, where the metal remains in the plane of the lever,thus presenting a comparatively wide lateral opening through the angeand between the bearings 3 and 4, in the space in-v dicated by 6. Thedown-turned fiange is curved inwardly and under at thehandleportion ofthe lever as indicated at 4a, and

the grip-portion of thehandle is provided with transverse ribs4b at theouter VCurved edge of the handle-grip, so as to prevent the fingers fromslipping.

The outer edge-portion of thel metal forming the lever B is bentdownwardly to provide the closure-gripping lug 5, andk is curvedinwardly and under, as indicated at 5a, to provide a suitable hand-gripfor the handle B. lThe Curved outer wall .of the handle B is likewiseprovided vwith transverse ribs 5b, to prevent the fingers from slipping.The metal at the outer edge of the main portion of the lever B is notvbent downwardly, but remains in the main plano of the lever, asVindicated at 7. vThus, the flange which forms the closure-grip 5 isinterrupted, or, in effect, cut away from the grip l5 to the pivotend ofthe lever.

From the description given, it will be understood that the body-portionsof the levers have a plane or substantially flat lower surface adaptedto rest upon the top of the can, while the closure-grips 3, 4.and 5 willgrip the circumferential portion of the jarclosure. v

The metal ofthe body-portions of the levers is struck upwardly to formexternal longitudinall strengthening ribs 8.

In the luse of the device, the levers are separated sufficiently toembrace the circumferential portion of the Closure between the lugs 3, 4and 5. When the handles are pressed together, the jar-closure is firmlygripped between the closure-gripping lugs and the closure may be readilyloosened and removed from the jar. It will be observed that theclosure-gripping lug 5 is a considerable distance from the pivot 2, theresult being that the lug 5 will grip the closure some distance beyond adiametrical line passing through the center of the Closure and a pointmid-way between the lugs 3 and 4. This will be true, even of quite alarge closure, so that it will be understood that the wrench isuniversal for a large range of sizes. Three closure-grips employed onlevers in this manner are sufficient to effectively grip the closure. Bymaking one of the levers of angular form, or providingl a lateralprojection which is integral with the lever, and which serves as apivot-ear, the construction is simplified, and the manipulation of thedevice is facilitated.

Patented May 22, 1917.

A device of the description given may be Vdurably made'and of handsomeappearance,

and may be manufactured thus at moderate cost.

The foregoing detailed description has been given for clearness ofunderstanding only, and no unnecessary limitation should be understoodtherefrom, but the appended claims should be construed as broadly` aspermissible, in view of the prior art.

What I claim as new, and desire to secure Y otally-connected sheet-metallevers having the lateral outer edge-portions oil the levers curveddownwardly to afford closure-gripping lugs and curved at thehandle-portions ci?` the levers to afford handle-grips, said Copies ofthis patent may be obtained for closure-gripping lugs being spaced toadmit the closure between them.

3. A jar-wrench comprising a lever having a lateral projection at oneend affording a pivot-'lug and having the outer lateral edge-portionprovided with a down-turned flange which is interrupted to affordclosuren gripping lugs7 and a companion lever pivotally connected withsaid pivot-lug and having its outer lateral edge-p ortion equipped witha closure-gripping lug.

Y 4l. A ar-wrench comprising a sheet-metal Y lever having alaterally-projecting pivot-lug at one end and having the outer lateraledgeportion of the metal bent downwardly to afford closure-gripping lugsand a handlegrip, space being left between the closure.`

gripping lugs to admit the closure, anda companion sheet-metal leverhaving one end pivotally connected with said pivot-lug and having theouter edge-portion of the metal bent downwardly to afford apivot-gripping lug and having the metal curved downwardly and under toafford a handle-grip.
